Аннотация:The article presents a study of the optical properties of 3,4,12,13,21,22,30,31-Octa-(2-naphthyl)-2,3-naphthalocyaninato zinc and 3,4,12,13,21,22,30,31-Octa-(2-naphthoxy)-2,3-naphthalocyaninato zinc in chloroform and thin film samples. Formed floating layers and Langmuir-Schaefer films of these compounds. The absorption and fluorescence spectra were obtained both for solutions of compounds and for multilayer Langmuir-Schaefer films. For multilayer films, it was shown that the Q-band position of the absorption spectra is 12-13 nm bathochromically shifted in comparison with spectra of solutions. It can be explained by the presence of intermolecular interactions in naphthalocyanine thin films which are characteristic of J-aggregates. In thin-film samples, fluorescence quenching occured due to the formation of a close-packed edge-on layer.
